At that time there was no test for succinylcholine and any accusation would have been met with slander. Succinylcholine is found in natural tissue and then there was no test to differentiate the two. The man made and natural also break down easily and cannot be found after a year. Today there is a way to differentiate the two. As far as the incident it was hearsay. To this day I am convinced she did it but nothing could be done then or now. I’ve heard of a few other murders done with succinylcholine but they had hard evidence of the act. The drug is hard to obtain these days but 35 years ago it was easy to get and loosely regulated.
Creepy. I presume you steered clear of this female Bluebeard.
